Glad you have the problem resolved! Usually, restore backup should not be a problem, unless the backup is really old. The rule of thumb is, you should create a new backup and discard any old backups each time after a new firmware update. Well, maybe keep the previous backup too in case you want to roll back to the previous version.
@casino Your black/white list is too long for the router to process in time. The router was still processing the list while the browser timed out. That’s why you get “bad gateway”. We’ll make improvement to this page in a future release. But for now, you need to make your list shorter.
Generally speaking, the black list & white list you enter in the profiles are for exception handling. They are not expected to be big lists. The majority of the filtering should be done by the DNS service you choose. If you get a list from the web, a lot of the entries might be filtered by the DNS service already.
Additionally, you can use the “approximate” match to make your black/white list shorter. Here are some examples:
If you entered “~\<pinterest.”, then you don’t need to enter the individual pinerest domains.
If you want to block all domains containing the word “proxy”, just enter “~proxy”. Similarly, “~porn” blocks all domains containing the string “porn”, “~unblock” blocks all domains containing the word “unblock”.
And, you can use port ranges instead of listing individual ports, e.g., “:6660-7000T” blocks all TCP ports from 6660 to 7000.
